Andoid not recognized as a mobile device

We've had several reports from Android users claiming that the Zimbra Web server doesn't recognize the Android as a mobile device and kicks them to the full Web page by default. Moreso, if they explicitly go to the mobile page and click around they sometimes get booted back to the full-featured Web page anyhow.

Is there any way to add to the list of devices that are treated as mobile devices by default?

Is there any way in Zimbra for admins to add strings as mobile devices like was done for drupal in the earlier link to address the same problem? Or is this something that would need to be added by developers to the base code?
